II. INTRODUCTION
This booklet contains the installation and operating instructions for your self-contained
air conditioner. There are a few precautions that should be taken to derive maximum
satisfaction from it. Improper installation can result in unsatisfactory operation or danger-
ous conditions.
Read this booklet and any instructions packaged with separate equipment required to
make up the system prior to installation. Give this booklet to the owner and explain its
provisions. The owner should retain this booklet for future reference.
III. CHECKING PRODUCT RECEIVED
Upon receiving the unit, inspect it for any damage from shipment. Claims for damage,
either shipping or concealed, should be filed immediately with the shipping company.
Check the unit model number, electrical characteristics, and accessories to determine if
they are correct.
IV. SPECIFICATIONS
A. GENERAL
The Packaged Air Conditioner is available without heat or with 5, 10, or 15 kW electric
heat. Cooling capacities of 2, 2
Units are convertible from end supply and return to bottom supply and return by reloca-
tion of supply and return air access panels. See cover installation detail.
The units are weatherized for mounting outside of the building.
The information on the rating plate is in compliance with the FTC and DOE rating for sin-
gle phase units. The following information is for three phase units which are not covered
under the DOE certification program.
1. The energy consumption of the ignition system used with this unit is 9 watts.
2. The efficiency rating of this unit is a product thermal efficiency rating determined
under continuous operating conditions independent of any installed system.
B. MAJOR COMPONENTS
The unit includes a hermetically-sealed refrigerating system (consisting of a compressor,
condenser coil, evaporator coil with capillary tube assembly), a circulation air blower, a
condenser fan, and all necessary internal electrical wiring. The cooling system of these
units is factory-evacuated, charged and performance tested. Refrigerant amount and
type are indicated on rating plate.
C. R-410A REFRIGERANT
All units are factory charged with R-410A refrigerant.
1. Specification of R-410A:
Application: R-410A is not a drop-in replacement for R-22; equipment designs must
accommodate its higher pressures. It cannot be retrofitted into R-22 units.
Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater than
R-22. Recovery and recycle equipment, pumps, hoses and the like need to have design
pressure ratings appropriate for R-410A. Manifold sets need to range up to 800 psig
high-side and 250 psig low-side with a 550 psig low-side retard. Hoses need to have a
service pressure rating of 800 psig. Recovery cylinders need to have a 400 psig service
pressure rating. DOT 4BA400 or DOT BW400.
Combustibility: At pressures above 1 atmosphere, mixture of R-410A and air can
become combustible. R-410A and air should never be mixed in tanks or supply
lines, or be allowed to accumulate in storage tanks. Leak checking should never
be done with a mixture of R-410A and air. Leak checking can be performed safely
with nitrogen or a mixture of R-410A and nitrogen.
⁄ , 3, 3 ⁄ , 4 and 5 nominal tons of cooling are available.
